Biohazard Warning Sign - Universal Symbol for Biological Hazards #76014 (License: Personal Use)

This image shows the internationally recognized biohazard symbol: a black trefoil (three interlocking circles) centered on a bright yellow equilateral triangle with a thick black border. Designed in 1966 by Charles Baldwin, the symbol is standardized under ISO 3864 and OSHA regulations for marking areas, containers, or equipment containing biological agents that pose a threat to human health. Its high-contrast color scheme ensures visibility and immediate recognition in emergency or controlled environments.

Used on laboratory doors, medical waste containers, biosafety cabinets, and transport packaging to signal the presence of pathogens, toxins, or other biohazardous materials; matches user intent for safety training, regulatory compliance, or hazard identification resources.
